l TO ALL WHOM IT MAY CONCERN:

Be it known that I, HIRAM STONE, of Cleveland,'in the county of Cuyahoga, and State of Ohio,'have invented certain new and useful Improvements in Fruit-Jars, Ste.; and I do hereby declare that the following is a full and complete description ofthe same, reference being had to the accompanying drawings, making a part of this specification, in which- VFigure l is a side view ofthe apparatus.

Figure 2 is a view ofthe top.

Like letters of reference refer to like parts in the views.

In iig. 1', A represents the jar in which the fruit is placed, and which may be constructed of any material, and of any desirable size or shape. I

`IB is the cover, between which and the edge of the jar is interposed a gasket, C, of rubber, or other suitable material, whereby the said cover is made to lit air-tight. p

D isan auxiliary jar, consisting of the same material, but much smaller, and is provided with a cover, E, so attached to the vessel, by-beingluted or otherwise, as yto be air-tight. Thisjar is' open at the bottom. and is placed upon the' top of the jar A for operation, as shown in iig. 1.

F is a metallic tube, fixed inthe top of said jar, and with which it communicates.

G is a stop-cock, and H a llexible tube, with which the jar is put in connection .with the airpump, as and for a purpose hereinafter shown.

Iis a stein, penetrating the cover, the lower end of which is provided with a cuplshaped socket, J, in which is inserted a cork or stopple, K, er the stopple may be attached to the stem by any adhesive material, and thus dispense'with the socket. Said stopple consists of rubber, or other airitnpervious material, oran ordinary cork may be used and afterwards sealed. i p

A is a coiled spring, surrounding the lower end of the stem, between the socket and cover, whereby the said socket and stem are retained in the position shown in the drawing. Said spring maybe placed ou the outside oi the jar, or other means usedfor that purpose The practical purpose ofthe auxiliary jar and appendages is for exhausting the air from the jar A, in which the fruit or other articles for preservation have boem-placed, and which being done, stopping the same in a.

vacuum, thereby preventing the air from re-entering the vessel while being corkedwand which is performed in the manner as follows, viz:

In thejar A, as before said, is placed the fruit or other articles, which is then closed by the cover B, resti ,l ing upon the gasket C. On the cover is new placed the auxiliary jar, and in such position as to bring the end l The frceend of the t'ube H is now attached to the air-pump,

of the stop'ple K immediately over the hole a. and thereby the air in the jar A is exhausted through thel hole a and auxiliary jar. v The vacuum thus obtained in the two jars is secured by thc stop-cock G. When the air is thus exhausted, the stopple K Vis then forced into the hole a by pressing down upon the stem I, which drives it into the hole, and'thereby becomes dislodged from the socket, and thus stops the hole permanently and air-tight. At the same time the external pressure of the air upon the cover forces itin close contact with the soft, yielding gasket laid between it and the edge of the jar, whereby the cover is made tight, a'nd thus excludes the air from the vacuum in whichthe fruit is kept. The auxiliary jar is now removed by letting in the air, by turning the stop-cock, thereby completing the hermetically sealing of the can or jar.

e described may be dispensed with, and the end of the flexible tube The stop-cock for d in connection withthe pump instead ofthe tube.

the stopple and gasket, are

easily and quickly performed', and insure perfect security to the fruit from the air, so that it may .be kept from decay, sound, fresh, and with its original flavor.4

The metallic tube and stop-coclabov II provided with-a thiinble, over which it is drawn, inserted in an aperture in the cover.

retaining the vacuum while it is being formed, may be use v In this manner, exhausting the air from the jar, and' sealing the same by I do not coniinemyself to any particular-shapedjar`,ror materialof which they may be made, the application of tbe auxiliary jar being alike applicable to all kinds that may be used for the preservation of fruits or other articles.

Nor do I confine 'myself to any particular-sized ousbaped auxiliaryjar. This jar maybe suiciently large to cover the entire fruit or preserving-jar, and the same results obtained, viz, stopping the hole a in a vacuum, and which may be done either by the stopple above described, or by the employment of valve placed over the hole and pusheclwtiglitly down upon' its seat by the stem. i i 'Y What I claim as my invention, and desire to secure by Letters Patent, irs- Y,

1. The stem I and spring A', as arranged, in combination with the auxiliary jar D, in the manner and for the purpose set forth. 4

2. The stem I and auxiliary jar D, in combintion with the jar A, for the purpose and in the manner substantially asisetfortb.
